Continuity mistake: When Lincoln shows up to Laz's house and Rae is hiding, she pulls the chain taught at one point. When she does, we see it pulled at the point on the radiator; the shot then cuts showing the entire radiator and the chain is now slack and in a small pile next to it.
Plot hole: Ronnie is shown returning to town a few days after leaving for deployment due to being discharged from the National Guard for his anxiety disorder. In reality, being medically discharged could take weeks, if not months depending on how long it takes the Army to make a decision. If the Army suspected he lied about not having anxiety in order to enlist that could add even more time for an investigation and possible criminal charges for fraudulent enlistment.
